FILING-CABINET.

v Specification of Letters Patent.

Patented Jan. 11, 1921.

Application. filed June 22, 1917. Serial No. 176,286.

T all whom it may concern Be it known that I, CHARLES F. MEILINK, a citizen of the United States of America, residing at Toledo, Lucas county, Ohio, have invented new and useful Filing-Cabinets, of which the following is a specification. This invention relates to features of the mounting and carrying of a member as to a support, especially for slidable withdrawal therefrom.

This invention has utility when incorporated in drawer mounting for extension from the case in sheet metal furniture filing cases. Referring to the drawings: Figure 1 is a side elevation of an embodiment of the invention in a four-drawer high sheet metal filing cabinet or case, parts being broken away;

Fig. 2 is a plan view of a partially withv drawn drawer from the case of Fig. 1, parts being broken away;

Fig. 3 is an enlarged section on the line III-III, Fig. 2; 3

Fig. 4 is a fragmentary perspective view of the forward end of the slide before the dog is in action;

Fig. 5 is a side elevation of the forward end of the slide with the dog withdrawn to drawer holding position; and

Fi 6 is an enlarged section on the line VI ,Fig. 2. 4

The case 1 has its forward or open front side bounded by the inwardly extending flange portion or style 2 cross connected by the channel portions 3 in providing the rectangular spaces to be closed by the drawer fronts 4 having the withdrawing handles 5. Extending rearwardlyalong the side of the case from near the style 2 are the carriers comprising the case engaging flange 6 of the angle bars having the inwardly projecting flange 7 providing track ways on its upper-and lower faces. The forward end of the track flanges 7 have the dip 8, while the rearward ends of these tracks 7 have the dip or drop sections 9.

Disposed to embrace the'track 7 is the slide or channel member 10 having the wider rearward portion 11 and the thinner forward avails of the clearance distance of t e style in the case as to the drawer for width stability and greater rigidity against lateral distortion than the narrower forward ortion 12 which in drawer withdrawal, in t e out- I play of the slide as to the drawer.

portion 12. This wider rearward ortion' ward travel of the slide issufliciently narrow to clear the style in protruding along the drawer side from the case 1.

The after or rear portion 11 of the slide 10- carr1es near its terminal the pin' 13 upon whlchls freely rotatable the grooved roller 14 normall r ding on the underside of the track 7 edially of its longitudinal extent the sl de 10 in its broader portion" 11 carries the pin 15 upon whichis loosely mounted the grooved roller 16,through itssupporting pin 15 propellingthe slide 10 in and out of the case and having two point bearing effectiveness in traveling on the underside of the track -7 while its short radius corner 17 away from the case 1 crowds automatically to position along the larger radius 18 of the lower track 19 of the channel 20 mounted in the recess 21 of the lower corner of the drawer 22. Adjacent the track 19, this '75 drawer channel 20 terminates'in an inwardl extending guide or flange 23 coacting with the groove of the roller 16 as well as the groove of the roller 14 to limit the lateral Vertically opposing the roller 16- and loosely carried by the pin 24 in the slide por-' tion 11 is the .roller 25 contactin the'track 7 directly opposite the bearingo the roller 16. Thi roller 25', also has two bearing contacts for slide and drawer propulsion relativel at the ratio of one to two out of and back into the case 1, and it has its curved edge 17 crowding the longer radius curve 18 of the u per track"26 of the channel mem her 20 of t e drawer 22. This'track 26 ter inmates inthe inwardly extending guide 27 opposing the guide 23. This guide 27 coacts w1th the groove of the roller 25 with some lateral play, in maintaining the slide in position as to the drawer.

- The forward narrow portion or section 12 of the slide 10 carries near its terminus the p1n 28 upon which is mounted for free rotatlon the narrow ungroovedroller 29 and like roller 14 is of less diameter than the. grooved rollers16, 25. r This roller 29 is .disposed for single track bearing on the track 26. The rear terminal roller 14 of the slide normally has but the single track bearing on the track 7. In the closing travel of the drawer 22, the after bend 9 in the track 7, acts through the length of the slide 10 and the forward terminal roller 29 to tilt the drawer front 4 up into easy entering clearing position, and this creates a frictional holding sufficient to maintain the drawer thus closed for easy withdrawal. I

In the withdrawing travel, the rear portion 11 of the slide 10 does not have any interlocking relation with 't he flange 7 of the case, but merely freely rides along one side thereof at one half the rate of drawer withdrawal. The terminal rollers 14, 29, limit the tilt of the drawer 22 on the middle fulcrum or four-point bearing rollers 16, 25, which in their loose mounting as to the slide, and due to the coacting of the track radius curves 18, anti-frictionally fix the rocking axis of the slide between this roller device pair 16, 25. Slight inequalities in metal thickness and structural variations of the tracks in this travel range are automatically cared for without any binding due to this self adjusting feature of the slide propelling rollers 16, 25, maintaining relation for smooth drivinat all times with the case and drawer. he bend 8 in the track 7 en.- gages the roller 16 to stop its outward travel before the widened portion 11 of the slide strikes the style 2. Forward of the closed position of the drawer 22 as to the rollers 16, 25, of the slide, the track 19, has thereacross the pin 30. In the outward travel of the drawer 22, the dog 31 having the pivot pin 32 is drawn from its back crowded position of Fig. 4 to which it is pushed by the drawer front 4 when closed, to its holding position of Fig. 5. This tra-vel of the dog 31 is permitted by the slot 33. If 1t is desired to remove the drawer from assembled relation with the case, when it is withdrawn to bring the slide into position shown in Fig. 4, the head of the dog 31 may be lifted to clear the pin 30 on further withdrawal of the drawer. In this lifting of the head of the dog 31, it must be over the pin 30,0r the pin will strike the dog extension 34and throw the dog out for pin engagement. When the drawer is withdrawn from the slide, the slide may be readily removed from the case.

The drawer 22 is normally carried the rollers 16, 29, with the roller 25 coacting to maintain snug relation of the after section of the drawer as to the slide, the roller 29 carrying the major portion of the load as the filing drawers are normally more heavily loaded at the forward end. This downward moment from the roller 29 is directly taken as upward" moment by the rear slide roller 14, permitted by the loose intermediate antifriction four point bearing device 16, 25, which further coacts with the roller 14 1n taking the drawer load through-the slide to the case. All rocking of the drawer load through the slide as to the case is fulcrum determined by the device 16, 25.

What is claimed and it is desired to secure by Letters Patent is:

1. A drawer, a case therefor, and a drawer extension providing a fulcrum between the drawer and case embodying a pair of rollers determining the axis of the fulcrum, one of which rollers has bearing coaction with the case for propelling the second roller, and said second roller having simultaneous bearing coactions with the drawer and case.
